I wouldn't recomend using metal Creepy Crawlers molds for food molds. If you look around online you will find lots of plastic food molds and there are some that have bugs. They don't cost much either. they often are sold as candy molds. But if you really want to eat Creepy Crawlers castings you might try what my friend Ed did a while back. He vacuformed plastic sheets around either the molds or their castings to get jello molds of the Creepy Crawlers.
